Hello list. I am looking for a suggestion on setting up an email system on a LAN. I am not really asking "How do I do this?", but rather, which software solutions should I use. I have never met too much in Linux that I can't figure out if I know where to look. What I have now .... SuSE 9.1 Pro, static IP, on WAN, Firewalled, SMTP port open, Postfix set to accept mail and route to one of 20 users on THAT machine. Postfix is configured to accept mail for 3 domains. All email for someuser@thisdomain or someuser@thismachine.thisdomain will be sent to someuser on this SuSE system. What I want to put into place .... The ability to route mail to anothermachine. So mail to someuser@thisdomain or someuser@thismachine.thisdomain would still got to someuser on the SuSE box, but mail to someotheruser@anothermachine.thisdomain would be set up to be delivered to mail software on anothermachine and mail from another machine would be sent out via routing through the SuSE system. I also want the ability to forward mail from someuser@thisdomain or someuser@thismachine.thisdomain to someotheruser@anothermachine.thisdomain and have it delivered to mail software on anothermachine. I have heard of fetchmail, pop mail, but I know nothing about any of this. I figured out postfix on the fly to get this far. All suggestions as to what software to use would be appreciated. Besides setting up the new software what changes do I need to make to my postfix main.conf file? Any HOWTO tips would also be appreciated. If there is a better list to direct these questions to please tell me. For completeness the other machine I am routing mail to is a Macintosh OS X system (10.4.1) All comments welcome. john
